Solder Smelting (Tin Alloys)Posted on July 10, 2012
is a form of extractive metallurgy; its main use is to produce a metal from its ore. This includes production of silver, iron, copper and other base metals from their ores. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind.
As most ores are impure, it is often necessary to use flux, such as limestone, to remove the accompanying rock gangue as slag.
